The Table Shows Success Rates For Two Computer Games Sessions. Whose Success Rate Changed The Most Between

Answers

Answer 1

Answer:

B. Brent

Step-by-step explanation:

       Let us turn the Session 2 scores into fractions so we have common units.

(John) 52% -> [tex]\frac{52}{100}[/tex]

(Alexis) 57.5% ->  [tex]\frac{575}{1000}[/tex]

(Brent) 39.5% ->  [tex]\frac{395}{1000}[/tex]

       Now, we can simplify them.

(John I divide by 2)  [tex]\frac{52}{100}[/tex] -> [tex]\frac{26}{50}=\frac{13}{25}[/tex]

(Alexis, I divided by 5) [tex]\frac{575}{1000}[/tex] -> [tex]\frac{115}{200} =\frac{23}{40}[/tex]

(Brent, I divided by 5)  [tex]\frac{395}{1000}[/tex] -> [tex]\frac{79}{200}[/tex]

       Now subtract Session 2 from Session 1 for each and figure out which one is the largest to answer the question.

(John) [tex]\frac{2}{3}[/tex] - [tex]\frac{13}{25}[/tex] = [tex]\frac{11}{75}[/tex] or about 0.146667

(Alexis) [tex]\frac{11}{20}[/tex] - [tex]\frac{23}{40}[/tex] = [tex]\frac{-1}{40}[/tex] or -0.025

(Brent) [tex]\frac{7}{10}[/tex] - [tex]\frac{79}{200}[/tex] = [tex]\frac{61}{200}[/tex] or 0.305

       Since the absolute value of 0.305 is greatest, B. Brent has the largest success rate change.

Jerry, Skyler and Kyle were measuring the tank (cylinder) for storing water tower on the hill. Working together Jerry and Skyler
determine the circumference was approximately 295.3 feet. Kyle measured the height to be about 40 feet. What is the potential
volume of the tank? (Round to the nearest tenth)

Answer?

Answers

Answer:

277 591.1 ft³

Step-by-step explanation:

First, use the formula for circumference to solve for the diameter.

Circumference = πd

295.3 = πd

295.3/π = d

94 ft = d

Then, divide the diameter by 2 to find the radius.

r = d/2

r = 94/2

r = 47 ft

Now, use the value of the radius with the given height in the formula for volume of a cylinder.

V = πr²h

V = π(47²)(40)

V = 277 591.1 ft³

Write an expression that represents the height of a tree that began at 6 feet an increases by 2 feet per year. Let y represent the number of years

Answers

Answer:

Yes.

Step-by-step explanation:

The expression 2y + 6 could be used to denote the tree's height.

What is an expression?

A number, a variable, or a mixture of numbers and variables, along with operation symbols, make up an expression. Two expressions joined by an equal sign form an equation.

Given, the height of a tree that began at 6 feet and increases by 2 feet per year. Let y represent the number of years

Expression = 2y + 6

Since the height of the tree starts at 6 feet thus positive 6 would be constant and it increases by 2 feet every year thus 2 would be the multiple of the variable that is y.

therefore, an Expression that represents the height of the tree would be 2y + 6.

in each linear equation identify the slope (m) and the y-intercept (b)

Answers

Answer:

a is D and b is C

Step-by-step explanation:

Slope is always with an x, b is always alone

Hey there!

Please remember that

in slope-intercept form, m is the slope, and b is the y-intercept.

Is y=4x-5 written in slope-intercept form (y=mx+b)? Sure! :)

Therefore, the slope, m, is 4, and the y-intercept, b, is -5.

Same with the second equation:

y=2/3-x

or

y=x-2/3

here, the y-intercept, b, is 2/3, and the slope, m, is -1.

Now, what's the equation of the line with a slope of 2 and a y-intercept of -7?

That's right, y=2x-7.

Hope everything is clear.

Aplumber charges a $75 flat fee for jobs lasting up to an hour and $30 for each hour of labor after the first hour. Which
expression models the cost of a job lasting h hours, when h is greater than 1?
O 75-30h
O 75+ 30(h-1)
O 75h+30
75(h-1)+30

Answers

Answer:-

[tex]\longrightarrow \sf 75+ 30(h-1) [/tex]

Solution:-

Given that :-

job last for h hours Cost of job lasting more than 1 hour = $30Cost for the first hour = $75

[tex]\leadsto[/tex]Remaining hours for which the job will last after first hour= (h-1)

Therefore,

Cost for subsequent hours = 30×(h-1)

= 30(h-1)

Total Cost for job = Cost for 1st hour + Cost for subsequent hours

[tex]\quad\quad\quad\quad\quad\quad\quad\quad\boxed{\sf{= 75+30(h-1)}}[/tex]

A piñata is a container filled with candy and is broke by hitting it with a stick. The probability that Amanda will break a piñata on her first his is 0.58. She will continue to hit the piñata until it breaks. If she does not break the piñata on a particular hit, the piñata is weakened and the probability that she will break it on the next hit is 0.14 greater than the probability on the previous hit. For example, if the piñata does not break on the first hit, the probability that it will break on the second hit is 0.72 (found by 0.58 + 0.14 = 0.72). Calculate the probability that Amanda does not break the piñata on the first hit and does break the piñata on the second hit

Answers

Answer:

0.3024

Step-by-step explanation:

Given the following :

Probability of breaking pinata on first hit = 0.58;

P(first hit break) = 0.58

P(does not break on first hit) = 1 - p(first hit break) = 1 - 0.58 = 0.42

P(2nd hit break) = p(first hit break) + 0.14 = 0.58 + 0.14 = 0.72

Hence, Calculate the probability that Amanda does not break the piñata on the first hit and does break the piñata on the second hit

P(does not break on first hit) * p(2nd hit break)

0.42 * 0.72 = 0.3024

The graph of f(x) shown below

Answers

Answer:

C

Step-by-step explanation:

the "-" sign can't be true, because that would have turned the whole graph of x² upside-down. but it is not.

so, we need a positive sign for the x term.

and the whole graph is shifted to the right. so the functional value of x of F(x) is now the same that happened "earlier" (for smaller x) with G(x). so, the argument "x" is now reduced (by 3 units, as the graph is shifted right by 3 units) in the calculation compared to the original G(x) calculation.

therefore, the ...(x-3)... expression is right.

so, positive sign and "(x-3)" is only in C.

So,

Note: Since the relationship between A, B, and C isn't known, it cannot be said for certain that 105 is the answer.

there is no C in the first 2 equations. There is no A or B in the last expression. I do not think you can solve this.
